Currently threads when core dumping overwrite each others cores so you lose
the registers of all but one.

Doing multithreaded coredump correctly is a lot more code than this.

Another useful application of an arbitary path name would be dumping to a
named pipe and having a dr.watson that logs the backtrace to the system log
(of course this has interesting deadlock possibilities when you're not
